Description

The utility model relates to the field of heat exchangers, namely, to radiators of the cooling system of internal combustion engines.

From the prior art, a radiator for a cooling system of an internal combustion engine is known, comprising intake and exhaust manifolds with bottoms, in which the ends of tubes fixed horizontally and parallel to each other in the lamellas are fixed by means of the mandrels of the tube cavities (see patent RU 112376, class F28F 1/00 , published on January 10, 2012). The disadvantages of the known device are the lack of heat transfer efficiency and high aerodynamic drag of the radiator as a whole.

The objective of the utility model is to eliminate these drawbacks. The technical result is to increase the efficiency of the radiator. The problem is solved, and the technical result is achieved by the fact that in the radiator of the cooling system of the internal combustion engine containing the intake and exhaust manifolds with bottoms, in which the ends of the tubes are fixed, fixed horizontally and parallel to each other in the lamellas by means of the mandrels of the tube cavities, the tubes are made flat-oval and arranged in two rows, with the rows oriented vertically, and the large sides of the tubes horizontally. The tubes are preferably fixed to the bottoms by means of flaring. The holes of the lamellas are preferably flanged. The radiator is preferably provided with fasteners in the car body and fasteners for additional equipment of the engine cooling and air conditioning systems.

In FIG. 1 shows a General view of the proposed radiator;

In FIG. 2 - node fixing the tube in the lamellas.

The radiator of the cooling system of an internal combustion engine consists of an intake manifold 1, an exhaust manifold 2 and a heat exchange part 3, providing heat removal from the coolant by a passing air stream. Part 3 includes flat oval tubes 4 fixed horizontally and parallel to each other in the lamellas 5 by burning the cavities of the tubes 4 (the design is such that after the burning process the outer size of the tubes 4 becomes larger than the holes in the lamellas 5, thereby the tubes 4 are tightly crimped by the lamella 5 ) The tubes 4 are arranged in two rows of 24 pieces each, and the rows are oriented vertically (this arrangement of tubes is called corridor), and the large sides of the tubes are horizontal. The ends of the tubes 4 are fixed in the bottoms 6 of the collectors 1, 2 by flaring and tightly crimped with rubber gaskets 7.

To improve heat transfer, the holes of the lamellas 5 are made with flanges 8. Such a design, together with fixing by means of a mandrel, ensures reliable thermal contact between the tubes 4 and the lamellas 5.

The collectors 1, 2 are equipped with fasteners 9 in the car body. The heat exchange part 3 is equipped with fasteners 10 for additional equipment for engine cooling systems (electric fan) and air conditioning (air conditioning radiator, used to cool the cabin air).

The proposed radiator is collected as follows.

The tubes 4 are installed in the design position in the lamellas 5 and are fixed by means of a mandrel. After that, the bottom 6 is installed on the ends of the tubes 4 and fixed by flaring the ends of the tubes 4. On the bottom 6, the outer part of the collectors 1, 2 is installed and crimped along the perimeter with the teeth of the bottoms 6. In this case, the ribs of the outer parts of the collectors 1, 2 are tightly pressed against the rubber gasket 7, which provides reliable tightness of the product.

The use of flat-oval tubes allows to increase the heat transfer area of the radiator by reducing the pitch between the tubes and making it possible to install more of them in a radiator of similar height. At the same time, the corridor arrangement ensures that the airflow efficiency for the back row of tubes will be almost the same as for the front one. In addition, the use of flat-oval tubes makes it possible to reduce aerodynamic drag and reduce turbulization of the air flow, which also positively affects the heat transfer of the radiator. Thus, the implementation of the proposed utility model can significantly improve the efficiency of the radiator.
